2 Claims. (x273 128) The present invention is directed to a playing piece or curling stone adapted to be used in the game Curlette, a modification of the Scotch .game curling, and which latter game is of uncertain origin, but which has been popular in Scot- 4 cludes the use of curling stones which may weigh asmuch as 70 pounds, but also includes the use of curling irons, that is, a playing piece for the game curling, in which the playing pieces are formed of iron, and which are used upon a rink of smooth and hard ice, in the same manner that curling'stones are used.

The playing piece or curling stone of the present invention is primarily adapted to be the playing piece used, as above stated, in the game Curlet't'e, in which it is proposed to form playing fields having exceedingly smooth surfaces of iron, over which the curling stone of the present invention may be caused to travel to or toward a scoring place; accordingly and in view thereof, it is a principal object of the invention to provide a playing piece or curling stone adapted to be used upon a surface other than ice.

A further object of the invention is to construct a curling stone which is adapted to move upon anti-friction means over a field of play.

A still further object of the invention is to provide a curling stone having anti-friction surfaces adapted to carry the curling stone in its movement toward a goal, and in which curling stone a degree of control in its movement toward a goal line or scoring place may be had by reason of freedom of movement afforded by said anti-friction means.

Another object of the invention is to construct a curling stone for fields of play based on land, and in which the playing piece has a low center of gravity to provide a great degree of inherent stability upon impact with other like playing pieces or curling stones.

A still further object of the invention is to provide a playing piece for the game Curlette, in which the weight of the playing piece or curling stone is carried upon a plural number of deeply set and. independently functioning steel balls restin up anti-friction means, and being so arranged with respect to the body of the curling stone that the steel balls cannot become dislodged therefrom upon impact.

and advantages" inherent therein, may be noted from the accompanying drawing, tion, and sub-joined claims.

In the drawing, of which there are two sheets: Figure 1 is a plan view of the playing piece or curling stone of this invention; and,

Figure 2 is a front elevational view thereof; while, Figure 3 is a bottom-plan view of the curling stone.

Figure 4 is a side elevational view of the curling stone. I i

Figure 5 is a longitudinal view in section showing interior construction and arrangement with respect to the steel balls upon which the curling stone moves, and with respect to the anti-friction means therefore.

t Figure 6 is a transverse sectional view taken substantiallypnline'6-6, in Figure 5, showing detailed construction not otherwise not-able.

The article of this invention, asindicated by the title, comprises a playing piece or curling stone ill for a game, and is formed asshown in the specificathe drawing, with a body portion I2, having in preferable form, substantialy flat and equispaced horizontal upper and lower surfaces I4 and I 6, bounded by circular sides l3 which merge with the top and bottom in a radius 20, while a handle 22 is fixedly secured upon the back-sweep of a metal strap 24, the end 26 of which is fixedly secured to the top surface I4 of the body portion l2 by means of a bolt and nut 28, the former of which extends transversely of the body l2 and in the medial vertical center thereof.

The body portion 12 as shown, is formed in matched half-portions 3B and 32, the abutting edges or faces of which are of stepped configuration whereby upon being drawn together by means of the bolt 28, the half-portions are in fixed relationship with respect to one another so that relative movement therebetwen is quite impossible.

As shown in the several figures of the drawing, the playing piece is adapted to move, over a playfield indicated by the line 2 1, upon a, plural number of steel balls 34, a segment only of which extends below the bottom surface l6 through openings 36 formed therein, and which openings are of smaller diameter than the diameter of the balls 34 so that after installation, the balls cannot be-' come disengaged from the curling stone with which they are individually associated, being in fact, imprisoned within the annular spaces 34a, 34b and 340 as defined by the upwardly extend-i lng' protrusions 39, 4| and 43, formed as integral elements of the half-portion 32, and the steel 'balls 50 of the bearing races 44 which rest upon annular steps 42 formed in the elements 39, 4|, and 43. V

The upper surfaces 48 of the bearing races are in flush contact with the lower faces of the cylindrical protrusions lfl, formed integrally withj and downwardly extending from the half-portion 30,

"so that when the elements 30 and 32 are drawn down tightly by the bolt 28, the bearing races 44 are fixedly secured in functional positign'and carry the weight of the whole of the assembly, for the bearings 50 ride uponztheupper suriace of the balls 34, which of course resist downward movement of the whole of the assembly, and hence support it in functional position-upon ,-a

play-field 2|, and in this connection it .s hou1d,be

mentioned, that'the extent of protrusion of the balls 34 from the body of the curling stone is the measure of clearance thereof with respect to the -play surface and hence controls the stability when-inaction. r r

The'preceding description isbelieved to beinclusive of essential" construction 3 involved in the play-piece or curling stone of this inventiomand that it willappear therefrom that I have conceived a novel construction in a play-piece or curling stone for the game Curlette, for use on play-fields forthisgame which are especially laid out and arranged so that the curlingstone may :be controllably advanced from a starting point to a scoring place.

-The curling stone of thepresent invention is intentionally-provided or madewith considerable Weight so that momentum-imparted thereto will Having thus described my invention, what I claim and desire to secure by Letter Patent is:
